Plenty of time in the near future I'm sure once they are older.
Our last night away was April 2011 (anniversary). In a couple of months we have a wedding in the country so we are staying the night without the kids. We might even do something for our next anniversary 2013.
ATM I'm saving for a family holiday 2015 to Fiji or Noosa for our 10 year, I want the kids with us!
